One illicitly seizing power (7)

I believe the answer is:

usurper

(Other definitions for usurper that I've seen before include "One wrongfully assuming" , "One wrongfully seizes power from another" , "One seizes power illegally" , "One supplanting (ruler) by force" , "One who illegally supplants another" .)

I've seen this clue in The Times.
